The Osprey Hydraulics Reservoir is a reliable hydration system for big adventures. Developed by Osprey in collaboration with Hydrapak, this reservoir is built to fit large-volume packs and support long hours on the trail. Its HydroStatic backplate gives it structure, making it simple to slide into a full pack while keeping a flat profile that sits comfortably against your back.
Osprey Hydraulics Reservoir: Designed for Serious Trails
The reservoir is easy to fill, clean, and use. Its wide opening allows quick filling with ice and water, and it can be turned inside out for thorough drying—a game-changer after a muddy hike. All materials are BPA-free, phthalate-free, and lead-free, and they meet FDA and EU food-safety standards.
How to Clean an Osprey Hydraulics Reservoir
Cleaning is straightforward: turn the reservoir inside out and hand wash with warm soapy water or use a mild cleaning tablet. Never put it in the dishwasher—heat can damage the seams. Rinse thoroughly and hang to dry with the opening open to ensure the inside fully dries, preventing mildew.
Get Rid of Plastic Taste
If your reservoir picks up a plastic taste, soak it in a solution of baking soda and water for a few hours, then rinse well. For persistent off-flavors, use a hydration bladder cleaning kit. Always air dry completely before storing.
